29 Questions
What is the primary function of the transport layer in end-to-end communication?
Managing the transportation of data between applications
Which of the following is a characteristic of the TCP protocol?
Use of port numbers for communication
What is the primary purpose of using port numbers in TCP and UDP?
To differentiate between applications
What is the purpose of TCP session establishment and termination processes?
To facilitate reliable communication
Which protocol does not guarantee the delivery of data?
UDP
What is the primary purpose of UDP client processes?
To establish communication with a server
When is it best to use UDP transmissions?
When speed is more important than reliability
What is the purpose of the three-way handshake in TCP?
To establish a connection between the source and destination
Which application uses UDP?
Video Streaming
What is the main difference between TCP and UDP?
TCP is connection-oriented while UDP is connectionless
What is the purpose of Netstat?
To examine TCP connections that are open and running on a networked host
What is the primary responsibility of transport layer protocols in the TCP/IP model?
Tracking the individual communication between applications on the source and destination hosts
What is the purpose of segmenting data in the transport layer?
To make data manageable and reassemble it at the destination
What is multiplexing in the transport layer?
Enabling many different communications from many different users on the same network at the same time
What is the main difference between TCP and UDP?
TCP provides reliable delivery, while UDP provides basic functions for delivery with no reliability
What is the primary purpose of the first step in the TCP three-way handshake?
To verify the destination device's active service and port number
What is the trade-off between TCP and UDP?
Reliability vs network overhead
What is the purpose of the sequence number in TCP reliability?
To reassemble segments into original order
Why does TCP make larger demands on the network?
Because it provides reliable delivery ensuring that all of the data arrives at the destination
What determines the amount of data that can be transmitted before an acknowledgement is required?
Window size
What is the purpose of the acknowledgement number in TCP reliability?
To confirm receipt of data
What happens in the second step of the TCP three-way handshake?
The server requests a server-to-client communication session
What is the primary difference between TCP and UDP?
TCP uses a three-way handshake, while UDP does not
What is the primary function of the Transport layer?
To provide multiplexing, segmentation and reassembly, and error checking
Which protocol is commonly used by applications that cannot tolerate delay?
UDP
What is the purpose of port numbers in the Transport layer?
To provide a 'tunnel' for data to reach the appropriate application
Which of the following applications typically uses TCP?
SMTP
What is the primary difference between TCP and UDP?
TCP is more reliable than UDP
Which protocol is used by applications that can tolerate small loss of data?
UDP
